When most people think of traffic safety cones, the color orange pops into mind. It is true that this is generally the color of the cones used outside. They are a fluorescent orange that will reflect light at night. However, even though orange is the primary color you see, manufacturers do make other colors, including lime green, yellow, and blue. The cones have a heavy base so that they do not easily tip over, even if it gets windy out. The color of the base varies, but it is generally black or the color of the cone. Some cones may have white stripes around them.
There really isn’t any trick to using a traffic cone. All you need to do is place them down in the area that you want to block off or in a pattern if you are trying to get people to park in certain areas. People know what the traffic cones signal, and they will generally proceed with caution until they know what they need to do and where they need to go. You will find that coupling the cones with other devices such as signs can be quite beneficial.
